The HI781`s low range of 0.00 – 5.00 makes it ideal for measuring the low nitrate levels found in saltwater aquariums.
Why are Nitrate levels important?
Excess nitrates in a reef system can lead to an overgrowth of undesirable algae and dinoflagellates. Alternatively, not enough nitrates can lead to starvation for SPS and other corals.
